The station monument coordinates and velocities of the designated 54 "core" stations are taken from: ftp://macs.geod.emr.ca/pub/requests/sinex/rfwg/IGS01P37_RS54.snx.Z and antenna heights from ftp://igscb/igscb/station/general/igs.snx. (Antenna reference point to L1 and L2 phase centers are from ftp://igscb/igscb/station/general/igs_01.pcv.) The jpl.acn file at the IGS CBIS has been updated to reflect the switch to the new reference frame. Please note that orbits, Earth orientation, SINEX station coordinates, and daily transformation files submitted to the IGS are still all free-network solutions, but are now aligned with IGS00. Due to potential problems, data from stations mentioned below were not considered for use in the global solution for the day indicated. (For geographical reasons, they may not have been used in any case.) WARNING: Data from PRN15 and PRN17 excluded the entire GPS week 1143. WARNING: Data from PRN29 excluded day 336. WARNING: Data from PRN04 excluded day 337. WARNING: Data from CAGS, DARW, DUBR, GUAM, LBCH, LHAS, LHUE, PETP, WUHN, YAR1 excluded day 336. WARNING: Data from DUBR, GUAM, IRKT, LAE1, LBCH, LHUE, PETP, SFDM, SOFI, SSIA, WES2, YEBE excluded day 337. WARNING: Data from HILO, HOLM, IRKT, LBCH, LHUE, PIMO, RIOG, SLOR, SSIA, WES2 excluded day 338. WARNING: Data from BJFS, HILO, IRKT, JAMA, LBCH, MSKU, PIMO, WES2, YAR1 excluded day 339.
